COOKING-STOVE.

SPECIPICATION forming part of Letters Patent No. 326,867, dated September 22, 1885.

(No model.)

To all whom it may concern:

Be it known that we, JOHN H. HARPER and DANIEL V. BROOKS, of Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Cooking-Stoves; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to portable ranges and stoves in which the products of combustion are carried off at the side of the range or stove, as distinguished from the back thereof. These stoves have heretofore been generally formed so that different stoves were necessary for a right or left hand smoke-escape, the stove requiring the different arrangement of the flues and dampers and of the oven-doors, according to whether it was employed as aright or a left hand stove, and it being necessary to specify, in ordering, which stove was desired. It is evident that in many cases where a right-hand stove suited the room in which it was first employed, in moving the stove to another room it would be found preferable to use it as alefthand stove, and this required the employment of several new castings and a large expense in changing the stove from right to left hand.

Stoves have heretofore been made with interchangeable pipes adapted to be secured by screws to the sides of the stove in such manner that the stove can be changed from right to left hand stoves, and vice versa, and with a deflecting-plate, which could be arranged, as set forth in Letters Patent No. 300,273, granted to \V. P. Lewis, June 10, 1884, on either side of the top flue, according to the manner in which the stove is arranged; but in all these stoves it was necessary to employ pieces of special shapes, attached to the body of the stove by screws which are exposed to the heat of the stove, and are soon burned out, so that they cannot be unscrewed, so that the stove can only be changed by skilled mechanics, and requires a long time to change it.

The object of our invention is to form an interchangeable right or left hand stove which requires no special shapes and can be changed in a few minutes by unskilled persons, while it provides a much more direct draft for heating the oven of the stove.

It consists, essentially, in providing the stove with smoke-escapes in each side wall thereof, having pipe collars, to which the smoke-pipe maybe secured in the ordinary manner, and with hinged dampers extending from each side half-Way across the top flue in front of the smoke-escapes to the center plate, so that by simply connecting the smoke-pipe with the pipe-collar on the opposite side of the stove, closing the pipe-hole formerly used by a cap, and operating the opposite hinged damper, the stove may be reversed and the products of combustion drawn from the opposite side, this change being made in a few minutes without the removal of screws or the employment of skilled mechanics.

It also consists in providing the bottom flue with smoke-escapes at each side, near the center, and with a damper for directing the draft, whereby in heating the oven the draft will pass directly through the top flue and back fine and be thrown by said damper to the front of the lower flue, and thence to the smoke escape, this smoke-escape in the bottom flue communicating with the smoke-pipe on either side of the stove, and the draft being reversed in said flue according to the side from which the smoke passes.

In the drawings, Figure 1 is a side view of our improved stove. Fig. 2 is a cross-section thereof on the line 1 1, Fig. 1. Fig. 3 is a longitudinal section on the line 2 2, Fig. 2. Fig. 4 is a horizontal section on the line 3 3, Fig. 3. Fig. 5 is a horizontal section on the line 4 4, Fig. 3.

Like letters of reference indicate like parts in each.

The stove or range illustrated is arranged as a left-hand stove, and has agrate, a, aslr pit a, oven 1), having doors I), and top plate, 0, having the lids 0, these parts being of the usual or any ordinary construction, except that instead of the smoke-escape being formed in the top plate, 0, as is usual in these stoves, it is formed in the side walls, o the top plate being of the same shape on each side. The

stove has the top flue, (I, back flue, e, and bottom flue, f, these flues being of the proper proportions and surrounding the oven 12 on three sides, the fourth side of the oven being against the grate a and ash-pit a, and receiving the heat directly from them.

On each side of the stove, communicating with the top flue, d, is the smoke-escape these smokeescapes extending through the side. walls,o",at about the center of the stove, under the central lids of an ordinary six-lid stove, the smoke-escapes having annular collars around them,over which the smoke-pipe h or the cap 9 fits, according to the side from which the products of combustion pass. The smokeescape not in use is covered by the cap g',corresponding to it in shapeand secured thereto by'a bolt or pin passing through said annular collar and the lip or flange of the cap. On the opposite side of the stove the smoke-escape g communicates with the smoke-pipe h, which is secured thereto in substantially the same manner as described with reference to the cap 9. This smokepipe h is provided with a T- pipe, h", preferably cast to shape,for the purposes hereinafter described,and in the T-pipe is the damper h,for closing communi cation between said pipe hand the upper flue, d, of the stove. In said flue d,extending halfway across from each side thereof, are the hinged dampers t, the outer ends of these dampers being in front of the smoke-escapes 9, so as to cut off direct (llilft from the grate to the smoke-escape in use, and the dampers extending back at a slight angle to suitable bearings in the center of the top flue, the dampers being thrown as far back as possible without interfering with the stove-lid hole, and on account of their diagonal position interfering less with the draft than when they extend directly across the flue. The dampers have suitable handles,i,extending through the side walls, 0.

In the center of the flue (1, extending longitudinally back from the inner ends of the dampers i,is the center plate, d, which divides part of the flue into two parts or chambers, the center plate being short and ending a sufficient distance from the back flue, e, to allow of the passage of the smoke and heat around the rear end of the plate and forward to the smoke-escape in use. These parts constitute the direct draft of the stove, and are employed when it is not desired to heat the oven, the products of combustion thus passing along the side of the upper flue and thence around the back of the center plate, d, to the smokeescape and smoke-pipe.

In order to arrange the stove to heat the oven for baking and like purposes, we have provided the lower flue, f, with the smokeescapes 70, passing through the side walls, a, in the central part of the stove directly under the smoke-escapes g, and the smoke-escape It not employed is covered with the cap or plate g in the same manner as one smoke-escape g in the upper flue, d. On the opposite side of this lower fine the smoke-escape la communicates with the smoke-pipe h by means of the elbow h, the elbow it being connected with the T-pipe h of the pipe it, above referred to, by means of a sheet-metal or other pipe, h, so that when the lower draft is employed the products of combustion pass down the back flue, e, and along the bottom flue, f, to the smokeescape is, and thence to the smoke-pipe. As, however, it is necessary to throw the products of combustion to the forward end of the lower flue, f, in order to heat the oven more evenly, the lower flue is provided with the longitudinal central plate, f which extends from a point just back of the smoke-escapes k forward toward the ash-pit wall a, suflicient space being left between the end of this plate f and the ash-pit wall to allow the free passage of the products of combustion around the forward end of this plate, and to cause the passage of the products of combustion around this plate f the L damper m is located in this bottom flue at the back of the center plate, f. This damper m is mounted on the same rod 0%, which is journaled in the side walls, 0 of the stove, and is provided with the handle n, the damper m having two wings, m m, at right angles to each other, so that when one wing is raised to close communication at one side of the plate f the other wing lies against the base of the flue and permits communication over said wing to the forward end of the flue, and thence around the forward end of the plate f to the smoke-escape 7c, and thence to the smokepipe, the products of combustion being thus thrown by means of said damper to one side or the other of the center plate. f,

and caused to pass to the forward end of the.

flue f before passing to the escape. Instead of the L- damper, two separate dampers may of course be employed, these dampers being arranged in substantially the same manner as the dampers t in the top flue.

The operation of our improved stove is as follows: Where the direct draft is desired, the.

damper h is opened, and the damper t on the side nearest the pipe is raised to close communication between the grate and that side of the flue d as shown in Fig. 3, and the smoke and products of combustion then pass along the opposite side of the flue d back of the plate d, and thence through the smoke-escape g to the smoke-pipe h. \Vhere it is desired to heat only the front of the stove, or to use the most direct draft obtainable, as in heating the stove quickly, this damper t may be lowered and the heat and products of combustion pass.

directly to the smoke-escape without passing back of the center plate, d, the stove being controlled by the damper h.

When it is desired to use the downdraft and heat the oven, the damper t is lowered, the damper it closed, and the products of combustion then pass on both sides of the center plate, d, through the flue d to the back flue, e, thence to the bottom flue, f, and forward through said flue until they strike the damper m, when they pass around one side of said flue, around the forward end of the center plate, f, to the smoke-escape k, and thence to the smoke-pipe It, the products of combustion being carried around three sides of the oven and to the forward end of the bottom flue, f, so that the oven is properly heated, whereby a direct draft for oven is provided.

When it is desired to arrange a stove as a right-hand stove, all that is necessary is to remove the T-pipe h elbow-pipe If, and the connectingpipe 70*, and to secure them to the smoke-escapes g and 7c, respectively, on the other side of the stove, close the other smokeescapes, y and k, by the capsg, turn down one hinged damper t and raise the other hinged damper i which has not been in use, and turn the L-damper in so that the wing m closes communication at the back of the smoke-escape k then in use, and the wing in opens communication at the other side of the plate f. These changes require but little time and are easily accomplished by unskilled persons,and the drafts in the stove are thus reversed, so that it operates in the same manner.

\Ve are aware of Letters Patent No. 185,997, granted to A. (J. \Villiams January 2, 1877, in which the products of combustion pass over the top of thestove, down one side of the back flue, forward and back through the bottom flue, and from the back flue to the smokeescape; but in such case the draft for heating the oven is not so direct as in my improved stove, in which the draft passes downwardly through the back flue and is reversed in the bottom flue, fromwhich it passes directly to the smoke-escape.

What we claim as our invention, and desire to secure by Letters Patent, is

1. A side-draft cooking stove or range having smokeescapes in each side wall thereof communicating with the top flue,and provided with pipe-collarsin combination with asmokepipe adapted to be secured to the pipe-collar around either smoke-escape, hinged dampers extending from each side half-way across the upper flue, and a cap closing the smoke-escape not in use, substantially as and for the purposes set forth.

and evenly heating the 2. A side-draft cookingstove or range having an oven, 1), upper flue, d, back flue, e, and lower flue, f, said lower flue having a smokeescape in the side wall thereof, in combination with a smoke-pipe adapted to be secured to said smoke-escape, and means in said lower flue for deflecting the current to the front of the flue and thence to the smoke-escape, substantiall y as and for the purposes set forth.

3. A side-draft cooking stove or range having-the lower flue provided with a smoke-escape on each side thereof, in combination with a smoke-pipe adapted to be secured to either of the saidsmoke-escapes, a cap or plate for closing the other smoke-escape, and a damper or dampers for reversing the draft in said lower flue, substantially as and for the purposes set forth.

4. A side-draft cooking stove or range having an upper flue, (Z, provided with smokeescapes at each side thereof, and a lower flue, f, provided with the smoke-escapes k at each side thereof, in combination with asmokepipe communicating on one side with said smokeescapes g and k, and a damper, h, closing communication between said smoke-escape g and said pipe, substantially as and for the purposes set forth.

5. A side-draft cooking-stove or range having a lower flue, f, provided with smokeescapes it on each side thereof, and a central plate, f, in combination with the smoke-pipe ll, communicating with one of said smokeescapes, and the damper in, substantially as and for the purposes set forth.

In testimony whereof we, the said JOHN H. HARPER and DANIEL V. BROOKS, have hereunto set our hands.
